Re: wiring diagram

All of these systems are related to the Body Control Module (BCM). Voyager. So a trip to the dealer should be the first thing you do. the dealer will access the BCM for stored Diagnostic Trouble Codes (DTCs).
I would also check ground G301 in the right hand "B" pillar. The "B" pillar is the one behind the front passenger seat. This is the ground for the BCM and power windows. Make sure it is nice and clean and tight. There is no PDF file with this avail without paying to get it. alldata is a pay for source. It sounds like the BCM may be the culprit here.

I have a 2003 Town and Country mini-van and I lost power to all my ... In addition to this my wipers, headlight controls, blinker controls, power door locks, and A/C/heat controls are out as well. The odd thing is that the power windows work, the power sideview mirrors work, the radio and ceiling lights also work.

you can't get whole diagram just sections,go to
(images of wiring diagrams(year,make model,motor size),and enter what your looking for ,=wiper motor,lighting,ignition . you can regester with auto zone and get free diagrams also.

The power windows are either fuses blown or regulator motors dead - check your power accessory fuses and go from there to check the regulator motors - try junk yard(s) before paying for as new window regulator.

The intermittent feature of the wipers - check/replace the switch that controls this feature (the most likely cause).

THe problem with ALL your dashboard electrical items failing at once, then coming back to life after a restart is a 12V breaker (not a fuse) in your fuse panel - it looks like a relay, but your maintenance manual (Haynes Manuals - $20 everywhere) will identify it as a breaker - its sticking in the "off" state and needs to be replaced, OR I SUSPECT THAT: moisture gets into the car somewhere and causes the breaker to TRIP to prevent the resultant short from burning up your mini-van in a brightly-lit vehicle fire, and when you turn the van on, the breaker is tripped - you restart the vehicle,(which turns out to be the proper procedure to reset a 12V breaker), and the breaker resets, and you drive off with working dashboard controls.

most likely the wiper motor is bad the second wire sould be a ground if you set meter to ohms you sould be able to get a low resistance to any good ground on the vehicle if the hot wire is hot any time key is on the bcm is controling the ground to operate moter and you should have a steady continuity on the ground side with switch on the fast postion an it will read on and off in the intermitant postion if both wires test good motor is bad when you replace motor let it cycle and shut it off before installing the arm on it

hello this depends alot of vehicles use the same relay for different things what you need to do is get a wiring schematic for your vehicle haynes usually has these at the back of there books you need to trace the wires in the book from your blower relay to see if anything else is tied into that relay then you will no for sure if it is strictly for blower only goodluck please rate
